PURPOSE:To lighten a tire remarkably, and while eliminate generation of turbulence of the structure of bead wire at the time of molding vulcanization of tire, and furthermore, positioning a bead without a hindrance at the time of tire molding. CONSTITUTION:Aramid fiber 3 are wound multiple times continuously in parallel with each other to be laminated in an inside hollow part of an annular member made of high elastic synthetic resin and having U-shape cross section of which outer diameter side is opened. A straight line part 4 is provided in the inner diameter side of the annular member 2, and while corner parts 5 of the annular member 2 are formed into circular. |
